CHURN.

Specification of Letters Patent.

Patented May 30, 1911.

Application filed August 27, 1910. Serial No. 579,350.

To all whom it may concern:

Be it known that I, JOHN R. GILDA, a citizen of the United States, and aresident of St. Louis, in the State of Missouri, have invented a certainnew and useful Churn; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

My invention relates to gear driven churns of the vertical dasher type,and has for its object the provision of a churn of simple, efficient anddurable construction, and which is readily adjustable to accommodatecrooks section.

' their ends.

or receptacles of different sizes.

The operation, construction and arrangement of the parts of theinvention are fully described in the following specification and apreferred embodiment thereof illustrated in the accompanying drawings,in which,-

Figure 1 is a side elevation of a churn embodying my invention, with thefly wheel partly broken away and the crock in cross- Fig. 2 is an endelevation of the same. Figs. 3, 4 and 5 show details of the frame headin which the operating mechanism is mounted, Fig. 3 showing a side view,Fig. 4 a top view, and Fig. 5 an end view of said frame head. Fig. 6shows a detail view of the dasher.

Referring to the drawings, the supporting standards 1 extend upwardlyand inwardly from opposite sides of the base-piece 2, to which they aresecured by bolts or screws 3. The base-piece may be either of wood orsheet metal. Braces 1 extend from the basepiece to the supportingstandards midway The upper ends of the standards 1 are provided withlongitudinal grooves on their inner faces to accommodate the frame-head5, and for convenience and cheapness of manufacture, I prefer to makeand have shown the standards as made of U- shaped angle-iron throughouttheir length.

The frame-head 5 is provided with top and bottom cross pieces 6 and 7and the side pieces 8, the latter being of such width as to slide freelywithin the grooves in the upper ends of the standards 1. The ends of thetop piece 6 project over the upper ends of the standards 1, forming afinish for the top of the frame and preventing the top piece 6 fromdropping below the upper ends of the standards. One end of the top piece6 projects a suilicient distance beyond the standard to afford a bearingfor the handle 9, which riveted or bolted to the top piece 6 through theaperture 6, thus affording a convenient means for gripping and steadyingthe frame with one hand while the crank is being turned with the other.

The frame-head 5 is provided with the cross piece 10, having apertures11 and 12 therethrough. In the aperture 11 is secured a spindle 13 uponwhich is mounted the internally toothed gear-wheel 14, provided withcrank-arm 15 and handle 16, through which power is supplied to operatethe churn. Journaled through the aperture 12 is a short shaft 17,carrying on one end the small gear-wheel 18, which meshes with thegear-wheel 1 1, and on the other end a fiywheel 19, the gear-wheel 18and fly-wheel 19 being keyed to the shaft so as to move in unison.

The top and bottom pieces 6 and 7 of the frame-head are provided withregistering apertures 6" and 7 a through which the parallel guide-rods20 slide freely. These guiderods are connected at their lower ends by ayoke 21, which yoke is in turn connected to the pin 22 near theperiphery of the flywheel by the rod 23, so that the revolution of thefiy-wheel causes a vertically reciprocating movement of the yoke.

The central portion of the yoke 21 is provided with a vertical aperturethrough which the upper end of the dasher-rod 24: passes, being held inplace therein by the thumb-screw 25, the dasher-rod carries at its lowerend the dasher 26, which is composed of four fan-shaped wings or fins27, as shown in Fig. 6. These wings or fins are formed with one or moreapertures 28 and have their sides curved downwardly, so as to prevent aconcave surface on their lower sides and a convex surface on their uppersides, thus materially aiding in the churning operation. By thisconstruction the cream and particles of butter are forced more readilythrough the openings in the dasher on the down stroke and the morereadily slide from the top of the dasher on its up stroke.

In order to accommodate the frame to crooks or receptacles of differentheights, I

make the frame-head adjustable in the standards 1 by means of slots 29in the standards, the frame-head being secured in any desired positiontherein by means of the set-screws 30. The crock or receptacle 31 may beof any desired shape within the limits of the size of the frame, and maybe held in position therein by means of lugs 32 on the base piece, asshown, or in any other suitable manner, as by stamping a flange or ribin the base-piece when the same is made of sheet metal. To assist inholding the crock or receptacle in position, I provide brackets 33,adjustably secured to the standards by means of the slots 34: andset-screws 35 and having arms 36 extending over and gripping the upperedge of the crock or re ceptacle between the two lugs 37.

I wish it understood that my invention is not limited to any specificconstruction or arrangement of the parts, except in so far as suchlimitations are specified in the claims.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is,

1. In a device of the class described, the combination of a framecomprising a base piece, and a pair of oppositely-disposed verticalstandards mounted thereon and having the upper ends of their inner facesformed with longitudinal grooves and their central portions formed withlongitudinal slots; a quadrangular head adjustably mounted in said frameand consisting of side pieces slidably fitted in said grooves and topand bottom cross-pieces connecting said side pieces; driving mechanismmounted in said head; and a pair of brackets adjustably mounted in saidslots and provided with inwardly extending arms formed at their freeends with devices for engaging a receptacle disposed between saidstandards.

2. In a device of the class described, the combination of a framecomprising a base piece, and a pair of oppositely-disposed verticalstandards mounted thereon and having the upper ends of their inner facesformed with longitudinal grooves, a quadrangular head adjustably mountedin said frame and consisting of side pieces slidably fitted in saidgrooves and top and bottom cross-pieces connecting said side pieces, thetop cross-piece having its ends projecting across the upper ends of saidstandards and adapted to rest thereon, to limit the move ment of saidhead in one direction; driving mechanism mounted in said head; andclamping means connected to said standards below said head for engaginga receptacle disposed between the standards.

3. In a device of the class described, the combination of a framecomprising a base piece, and a pair of oppositely-disposed ver ticalstandards mounted thereon and having the upper ends of their inner facesformed with longitudinal grooves; a quadrangular head adjustably mountedin said frame and consisting of side pieces slidably fitted in saidgrooves, top and bottom cross-pieces connecting the side pieces andformed with alining apertures, and a vertical cross-piece connecting thefirst-named cross-pieces and formed with a pair of apertures located oneabove the other; a spindle journaled in the one of the apertures in thevertical crosspiece; a gear secured to said. spindle and provided withan operating handle; a shaft journaled in the other aperture in saidvertical cross-piece; a fly-wheel and a gear secured to said shaft, saidgear meshing with the first-named gear; a pair of vertical guide rodsslidable in the apertures in said top and bottom cross-pieces; a yokeconnecting said guide rods adjacent the lower ends thereof; a pinsecured to said fiy-wheel; and a rod connected at one end to said pinand at the other end to said yoke.

In testimony whereof, I have hereunto signed my name to thisspecification in the presence of two subscribing witnesses.
